ACETYLENE-GAS Specification of Letters Intent,

.ln tented Sept. 23, i1 913.

Application filed November 29, 1912. Eermi No. 734.],99.

T 0 all whom it may concern:

Be it known that I, W oLroANo Gscnwimnman, a citizen of the UnitedStates, residing at (.lleato-n, in the county of l\[uhlenberg and Stateof Kentucky, have invented new and Improvements in rtcetylene-Gz'lsLamps, of which the following is a specili-- cation.

This invention. relates to acetylene gas lamps, the object in view beingto provide a lamp of the characttn' referred to, especially designed forthe use of miners, the said lamp being accessible in all of its partsand capable of being easily and quickly put together, after being:tilled, and also cn'lbodylug novel means for coupling the sections ofthe lamp together, and at the same time sup nn-tirethe lamp as a wholeupon the hat or helmet of the minor.

\Vith the above and other objects in view, the invention consists in theconstruction, cornbinatimi and arrangement; 01'' parts, as will behereinafter more fully described, illustrated in the itttnlll hlllylHQdrawings, and pointed out in, the claim hereunto appended.

In the drawings: Figure l. is a perspective view of the complete lamp.Fig. 2 is a vertical section through the same. Fig". 3 is a top planview thereof. Field; a side clevation of th lamp, showing the twosections locked together. Fin. 5 is; a similar View, showing the locktl'lrovm back. I

The miuers lamp contemplated in this in vention comprises a bottomsection 1, and a top section 2, said sections being substantially squarein cross section and of approximately equal size.

The bottom section 1. forms a single compartment in itself, and isadapted to receive the carbid, said bottom section 1 being open at thetop when detached from-the top section, and the top section forming aclosure or cover therefor. "he bottom section is also provided with theoutwardly projecting keepers or projections 3 at opposite sides thereof,for a purpose which Will hereinafter a p p ca 1. I

The top section 2 is divided oti' nteriorly to iform a gas chamliier lin the bot! rthercof, the bottom of said gas chamber being: pei-l mated.as shown at 5, to admit the gas generated in the carlnd holdingsection 1. A burner tube 6 communicates with the gas chamber referredto, and provided with a suitable burner tip 7, back of which is arrangeda reflector 8 attached to the top soction, as shown.

l rojccting downward from the Water com mrtment or chamber locateddirectly over the gas chamber is a guide tube 9, in which mounted thestem 10 of a valve 10',

the stem of which projects up through the top wa ll of the upper section2, and pro vided at its upper end with a cross head ll, the ends ofwhichare formed into hooks 12. These hooks 12 are adapted, when the stemis pushed dow nvard, to interlock with an other stationary crosshead orkeeper 13 hearing a fixed relation to the top section 2. When these twocross heads are interlocked, in the manner illustrated, the valve isclosed, thereby muting oh the llow of water from the water chamber intothe carbid chamber. l'iy partially revolving the stem of the 'alve bymeans ol. the cross head thereon, the latter may be thrown out ofinterlocked engagement with the fixed cross head or keeper and drawnupward, thereby allowing the water to How through the tube into thecarbid chamber, until. a sufiicient amount of gas has been generated forthe nuposes ol the miner.

il ldesignates a plug for closing the filling aperture 1.5 in the top ofthe upper Section 2.

In order to fasten the two sections of the lamp together, and at thesame time provide for supporting the lamp as a whole on the minefis hator helmet, a forked lever 15 is provided, the arms of said forked leverstraddlinp the top section of the lamp and being pivotally connectedthereto at 16. To the central portion or crown of the forked lever isattached a hator l'iclmct-engaging hook 17, the point of which extendsdowir ward, said hook also acting as a handle for coupling or uncouplingthe two sections of the lamp.

Iivotally connected to the oppositelylying arms of the forked lever arecoupling hooks 18, the lower hooked ends of which are adapted to engageunder the keepers or projections at opposite sides of the 'cttom section1 of the lamp.

By placing the hooks 18 in engagement with the keepers on the bottomsection of the lamp, and then rocking the forked lever by means of thecombined hook and handle, the two sections of the lamp are drawn tiohtlytogether and rigidly held, aftcr which the ,or recharging the acetylenelamp,

hook on the crown of the lever may be inserted in the rim of the hat orhelmet.

An emergency oil burner 19 is inserted in a compartment especiallyprovided therefor in the top section of the lamp, said pocket beingwater-proof, so as to exclude the water contained in the upper chamberof the top' section. This emergency lamp is adapted to be filled withoil, and embodies a wick 20, a filling cap 21, and a hook 2% adaptingsaid emergency burner to be applied to the miners hat, while he isengaged inrefilling The emergency burner is wholly contained within theplane of the top section of the lamp,

' and does not interfere withthe use thereof in any way.

23 designates a gasket forming a tight joint between the upper and lowersections of the lamp. v

. The plug 14 and the cap 21 are attached Gopies of this patent may beobtained for pivotally attached thereto, a supporting 30 hook projectingfrom the crown of the fork, coupling hooks pivotally connected to theside arms of the forked lever, and projec tions on the bottom sectionengaged by said couplinghgoks.

In testimony whereof I aflix my signature in presence of two witnesses.
